Undecided questions

You can try looking for more people to chat to.

You can speak with me, I'm Italian I can teach you something :)

Hello! I think one of the issues with finding partners to chat with is the huge time difference between China and the United States. I would be happy to chat with you so you can practice your English. I am just starting to learn Mandarin and can only say a few sentences. I'm a bit shy about speaking Mandarin because I can say so little. Do you want to set up a time to Skype this weekend? Sunday afternoon. What works for you?
